Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

• Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
• Do NOT click the Reset button on the Safe Mode start window

• https://support.mozilla.org/kb/Safe+Mode
• https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes

Try to set all plugins to "Ask to Activate" on the "Firefox/Tools > Add-ons > Plugins" page.

There are other things that need your attention.

Your System Details List shows multiple Flash plugins.

• Shockwave Flash 11.9 r900
• Shockwave Flash 17.0 r0

You can find the installation path of all plugins on the about:plugins page.

• http://kb.mozillazine.org/Issues_related_to_plugins#Identifying_installed_plugins

You can check the Flash player installation folder for multiple Flash player plugins and remove older version(s) of the plugin (NPSWF32) and possibly (re)install the latest Flash player.

• (32 bit Windows) C:\Windows\System32\Macromed\Flash\
• (64 bit Windows) C:\Windows\SysWOW64\Macromed\Flash\

After restarting in safe mode with all plugins set to ask to activate and all extensions to disable. Firefox still crashes. I did remove the old versions of flash.

I noticed you mentioned the "Enhanced" new tab page. If you use the "gear" icon to change to the "Classic" page, this problem does not occur?

I'm not sure whether the issue is using the link or changing the page in the tab. If you load the page in the same tab as the new tag page using either of the following alternate methods, does it avoid the crash:

• right-click > Copy Link Location, paste into address bar, press Enter
• drag the thumbnail image to the address bar (cursor will be there but image will stop moving below the bar) and drop/release there

If you create a new Firefox profile, does the problem still persist?

Even in safe mode when I try to open a new tab and quickly try to change the gear icon to classic it will crash. I uninstalled and reinstalled but the problem persists.

I believe I have solved the problem from seeing another post: https://support.mozilla.org/en-US/questions/1056211 I had to enter the firefox browser preferences and manually change the browser.newtab.url link.

i was having similar but your fix didn't work what i had to end up doing was this did a search in about:config for "tiles", and the problem was this layers.enable-tiles;False , setting to True solved this
